FIG. 1 is a flow chart of a network registration method of a mobileterminal according to an embodiment of the present disclosure. Thenetwork registration method is configured in a network registrationapparatus of a mobile terminal for illustration. Embodiments of thepresent disclosure may be applied in a procedure when the user uses themobile terminal to register 4G network, or may be applied in a procedureof registering 3G network or 2G network, which are not limited. Themobile terminal may be hardware devices with various operating systems,such as a smart phone, a tablet PC, a PDA, and an E-book.

The network registration method of the mobile terminal can includefollowing actions in blocks illustrated in FIG. 1. The method can beginat block S11.

At block S11, an element T_(i) in a time array is read in response todetermining that a predetermined abnormal event occurs when the mobileterminal registers a first network, in which the time array is {T₁, T₂,. . . , T_(i), T_(i+1), . . . , T_(n)}, i is a positive integer between1 and N, and N is a positive integer.

Embodiments of the present disclosure are illustrated in a case in whichthe mobile terminal registers the 4G network.

The execution body of embodiments of the present disclosure may be, forexample, a built-in modem of the mobile terminal.

Alternatively, the predetermined abnormal event includes TAU beingrejected.

The first network is 4G network.

It can be understood that, during the procedure in which the user usesthe mobile terminal to access the 4G network, a response indicting afailure of registering the network may occur, in which the failure ofregistering the network may be caused by the TAU being rejected, or maybe caused by other reasons.

In embodiments of the present disclosure, when the mobile terminal failsto register the network due to the TAU being rejected, the time arraymay be started and the element T_(i) in the time array may be read. Forexample, when the mobile terminal initially fails to register the firstnetwork, the element T₁ may be read from the time array {T₁, T₂, . . . ,T_(i), T_(i+1), . . . , T_(n)}, and the mobile terminal is controlled toregister the network with different rate, for example, 2G network or 3Gnetwork, during the time interval of T₁, to ensure that the mobileterminal can normally access to Internet. When the mobile fails toregister the first network the second time, the element T₂ may be readfrom the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, andso on. The element T_(i) in the time array {T₁, T₂, . . . , T_(i),T_(i+1), . . . , T_(n)} is read alternately, to enhance the success rateof registering the first network by the mobile terminal, which is notlimited.

A value of the element T_(i) in the time array may be set by the userbased on his own demand, or may be preset by the manufacturer of themobile terminal, which is not limited.

At S12, the mobile terminal is prohibited from registering the firstnetwork, and is controlled to register a second network.

In embodiments of the present disclosure, the second network has atransmission rate different from the first network. For example, thesecond network may be 2G network, or 3G network, which is not limited.

In embodiments of the present disclosure, when the mobile terminalinitially fails to register the first network and when the mobileterminal fails to register the first network due to the TAU beingrejected, it is possible to control the mobile terminal to switch toregister the network with different rate, for example, 2G network or 3Gnetwork, in the time interval of T₁. Alternatively, when the mobileterminal alternately reads the element T_(i) in the time array {T₁, T₂,. . . , T_(i), T_(i+1), . . . , T_(n)}, the mobile terminal may switchto register the network with different rate in the time interval ofT_(i), thus effectively ensuring that the mobile terminal can normallyaccess to Internet.

At S13, the timer is started to time, to obtain a first counted time.

In embodiments of the present disclosure, while the mobile terminal isprohibited from registering the first network and is controlled toregister the second network, the timer may be started to time, to obtainthe first counted time. The mobile terminal may determine whether theduration of registering the second network reaches T_(i) according tothe first counted time, which is not limited.

At S14, it is determined whether the first counted time reaches T_(i).

In embodiments of the present disclosure, it is possible to determinewhether the first counted time reaches T_(i), to determine whether totrigger the mobile terminal to re-register the first network, which isnot limited.

In some embodiments, as illustrated in FIG. 2, following action may beperformed after S14.

At S21, when the first counted time does not reach T₁, the mobileterminal is continuously controlled to register the second network.

In this action, by continuing to control the mobile terminal to registerthe second network when the first counted time does not reach T_(i), itcan ensure that the user can register the network with different ratewhen the TAU is rejected by the network, avoiding the connectionlessnetwork service state, and effectively improving the user experience.

At S15, when the first counted time reaches T_(i), a first identity isobtained, in which the first identity is the TAI of an adjacent cell ofa cell where the mobile terminal is when registering the first network.

In embodiments of the present disclosure, when the first counted timereached T_(i), the TAI of the adjacent cell of the cell where the mobileterminal is when registering the first network may be obtained, tocontrol the mobile terminal to re-register the first network accordingto the TAI of the adjacent cell.

The TAI of the adjacent cell of the cell where the mobile terminal iswhen registering the first network may be obtained by technologies inthe related art, which will not be elaborated here.

At S16, the mobile terminal is controlled to re-register the firstnetwork according to the first identity.

In embodiments of the present disclosure, when the mobile terminal failsto register the first network the first time due to the TAU beingrejected, the mobile terminal reads the element T₁ in the time array{T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}. In the time interval ofT₁, the mobile terminal is prohibited from registering the firstnetwork, but switches to register the second network, and accesses tothe second network in the time interval of T₁. Then, when the countedtime of the times reaches T₁, the mobile terminal is controlled tore-register the first network according to the TAI of the adjacent cell.If the registration successes, the mobile terminal accesses to the firstnetwork. If the registration fails, the mobile terminal reads theelement T₂ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . ,T_(n)} and resets the timer for timing again, and switches to registerthe second network again in the time interval of T₂. When the re-countedtime reaches T₂, the mobile terminal is controlled to register the firstnetwork again according to the TAI of the adjacent cell of the cellwhere the mobile terminal is when registering the first network thesecond time. By that analogy, the element T_(i) in the time array {T₁,T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, untilthe mobile terminal registers the first network successfully, which isnot limited.

In this embodiment, by controlling the mobile terminal to register thesecond network when the predetermined abnormal event occurs during themobile terminal registers the first network, it can ensure that the userregisters the network successfully, and by obtaining the first identity(the TAI of the adjacent cell of the cell where the mobile terminal iswhen registering the first network) when the first counted time reachesT_(i), and controlling the mobile terminal to re-register the firstnetwork according to the first identity, the mobile terminal canregister the network of the cell with different TAI when the current TAUis rejected by the network, thus effectively enhancing the success rateof registering the network.

In embodiments of the present disclosure, when the mobile terminal failsto re-register the first network due to the TAU being rejected, themobile terminal reads the element T₂ in the time array {T₁, T₂, . . . ,T_(i), T_(i+1), . . . , T_(n)}. In the time interval of T₂, the mobileterminal is prohibited from registering the first network, but switchesto register the second network, and accesses to the second network inthe time interval of T₂. Then, when the counted time of the timerreaches T₂, the mobile terminal is controlled to re-register the firstnetwork according to the TAI of the adjacent cell. If the registrationsuccesses, the mobile terminal accesses to the first network. If theregistration fails, the mobile terminal reads the element T₃ in the timearray {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} and resets thetimer for timing again, and switches to register the second networkagain in the time interval of T₃. When the re-counted time reaches T₃,the mobile terminal is controlled to register the first network againaccording to the TAI of the adjacent cell of the cell where the mobileterminal is when registering the first network the second time. By thatanalogy, the element T_(i) in the time array {T₁, T₂, . . . , T_(i),T_(i+1), . . . , T_(n)} is read alternately, until the mobile terminalregisters the first network successfully, which is not limited.

At S315, information about the TAU being rejected is obtained and sentto the server, such that the server backs up the predetermined abnormalevent according to the information.

Alternatively, the mobile terminal obtains the information about the TAUbeing rejected by the network, and sends the information to the server,such that the server backs up the predetermined abnormal event accordingto the information.

In this embodiment, the time T_(i) of the time array is set by the user,and thus personalized setting of the time array can be realized, andgenerality of the network registration method of the mobile terminal canbe improved. By controlling the mobile terminal to register the secondnetwork when the predetermined abnormal event occurs during the mobileterminal registers the first network, it can ensure that the userregisters the network successfully, and by obtaining the first identity(the TAI of the adjacent cell of the cell where the mobile terminal iswhen registering the first network) when the first counted time reachesT_(i), obtaining the second identity (the TAI of the adjacent cell ofthe cell where the mobile terminal is when re-registering the firstnetwork) when the second counted time reaches T_(i+1), and controllingthe mobile terminal to re-register the first network according to thefirst identity or the second identity, the mobile terminal can registerthe network of the cell with different TAI when the current TAU isrejected by the network, thus effectively enhancing the success rate ofregistering the network.

In order to illustrate the actions of the above embodiments moreclearly, an example is given as follows.

As an example, when the time array is {1 min, 6 min, 12 min}, itindicates that the mobile terminal reads the element 1 min in the timearray {1 min, 6 min, 12 min} when the mobile terminal fails to registerthe 4G network the first time due to the TAU being rejected. In the timeinterval of 1 min, the mobile terminal is prohibited from registeringthe first network, and switches to register the 2G or 3G network. Themobile terminal accesses to the 2G or 3G network in the time interval of1 min. then, when the counted time of the timer reaches 1 min, themobile terminal is controlled to re-register the 4G network according tothe TAI of the adjacent cell. If the registration successes, the mobileterminal accesses to the 4G network. If the registration fails, themobile terminal reads the element 6 min in the time array {1 min, 6 min,12 min}, and re-starts the timer for timing. In the time interval of 6min, the mobile terminal switches to register the 2G or 3G networkagain. When the re-counted time reaches 6 min, the mobile terminal iscontrolled to register the 4G network again according to the TAI of theadjacent cell of the cell where the mobile terminal is when registeringthe 4G network the second time. If the registration successes, themobile terminal accesses to the 4G network. If the registration fails,the mobile terminal reads the last element 12 min in the time array {1min, 6 min, 12 min} and re-starts the timer for timing. In the timeinterval of 12 min, the mobile terminal switches to register the 2G or3G network again. When the re-counted time reaches 12 min, the mobileterminal is controlled to register the 4G network again according to theTAI of the adjacent cell of the cell where the mobile terminal is whenregistering the 4G network the third time. By that analogy, the mobileterminal then re-searches for the 4G network every 12 min. In this way,it can ensure that the user can register the network with other ratewhen the TAU is rejected by the network, avoiding the connectionlessnetwork service state.
